Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 illustrate a schematic configuration of an image capturing apparatus according to an embodiment of the present invention.

2 and 3, the image acquisition device 200 according to an embodiment of the present invention is provided in a mounting stand vertically arranged to obtain an image while serving as a street lamp, the body unit 210, The camera 220, the detection sensors 231 and 232, the illumination sensor 240, the lighting unit 250, and the controller 260 may be included. Hereinafter, the function of each component will be described in detail.

Body 210 is a component constituting the basic skeleton of the image acquisition device 200, the camera 220, the sensor 231, 232 and the illumination unit 250 is disposed at the bottom, the illumination sensor 240 on the top ) Is disposed, and the controller 260 may be disposed inside the body portion 210.

The camera 220 is a CCTV device that performs a function of acquiring an image.

The detection sensors 231 and 232 detect a human body located near the image acquisition apparatus 200. For example, the detection sensors 231 and 232 may include a passive infrared sensor (PIR) sensor 231 for detecting a human body in far infrared rays, and a microwave sensor 232 for detecting a human body using microwaves in a 5 GHz frequency band. have.

The illuminance sensor 240 measures illuminance of a space where the image capturing apparatus 200 is located. As one example, the illuminance sensor 240 may be a digital illuminance sensor having an exact value of 1 lock.

The lighting unit 250 emits light through the LED device using a DC power or commercial AC power. At this time, the lighting unit 250 serves as a street lamp, and at the same time, the camera 220 emits light in order to obtain a clear image in a low illumination.

The lighting unit 250 will be described in more detail as follows.

In the conventional DC LED element used for illumination, the input voltage and the current applied to each LED element are 3V and 350mA, and when the series and parallel are mixed to form a lamp, the input voltage is DC 25V to 48V. In this case, a switched mode power supply (SMPS), that is, a power supply, which is an AC / DC converter is necessary. In the case of the DC-type LED device, the light output, the brightness, etc. are always output constantly, which is a good evaluation as a light source of the lighting device, on the other hand, there is a problem that the power supply is frequently broken. Due to this problem, the demand for LED lighting using a DC-type LED device is not expanded.

Therefore, the lighting unit 250 of the present invention improves the above problems and uses a commercial AC power source. However, the present invention is not limited thereto, and the lighting unit 250 may be designed to enable a DC driving.

4 is a diagram illustrating a circuit configuration of a lighting unit 250 using commercial AC power according to an embodiment of the present invention.

4, the lighting unit 250 includes a plurality of LED elements 251 connected in series or in parallel; The driving circuit unit 252 for driving the plurality of LED elements 251 and the EMI protection circuit unit 253 for preventing electromagnetic interference (EMI) of the driving circuit unit 252.

The lighting unit 250 of the present invention may use Percent Flicker as it is, or may use a circuit that improves the percent flicker. If the circuit that does not improve the percent flicker is used as it is, the insertion position of the camera 220 and the sensors 231, 232, and 240 may be adjusted, thereby preventing the problem of disturbing the operation function. Not designed. It also complements noise and withstand voltage enhancement circuits. The noise improvement circuit inserts a ground circuit and secures the PCB copper plate as wide and wide as possible in the PCB artwork design to prevent malfunction due to interference between electronic devices generated by electronic devices. In addition, by matching the ground pattern and the power supply pattern in parallel like the multi-PCB inner layer, noise can be actively blocked due to the effect of an infinite disk.

On the other hand, the DC LED driving circuit inevitably generates switching noise by the on / off operation of the power conversion element in the switching mode power supply (SMPS), thereby causing electromagnetic interference problems. However, since AC drivers are mostly composed of linear circuits, they do not have EMI problems due to low power noise at low power. However, when the power consumption of LED devices increases, EMI performance required by lighting standards is required. Can not be satisfied.

Therefore, since the lighting unit 250 of the present invention is 80Watt outdoor lighting, when the commercial AC power is used as it is, there is a high possibility that a malfunction of the device occurs due to noise interference between electrical devices. In order to solve this problem, an EMI protection circuit unit 253 is required.

In detail, the EMI protection circuit unit 253 includes a first resistor R ₁ , a second resistor R ₂ , a third resistor R ₃ , a capacitor C ₁ , a diode D ₁ , and a zener diode ( ZD ₁ ). At this time, one end of the first resistor R ₁ , _one end of the second resistor R ₂ , and one end of the diode D ₁ are connected to a positive electrode terminal _VP (+) of a commercial AC power source. The other end of the first resistor R ₁ and the other end of the second resistor R _{2 are} connected to one end of the third resistor R ₃ and the other end of the diode D ₁ . In addition, the other end of the third resistor R ₃ is connected to _one end of the capacitor C ₁ , _one end of the zener diode ZD ₁ is the other end of the diode D ₁ , the other end of the first resistor R ₁ , The other end of the second resistor R ₂ and one end of the third resistor R ₃ are connected, and the other end of the capacitor C ₁ and the other end of the zener diode ZD _{1 are} connected to the negative electrode terminal of the commercial AC power supply ( Is connected to V _N (-)). Then, the commercial AC power source (+) electrode terminals (V _P (+)) is a control chip (for example in the input stage and the driver circuit portion 252 of the first LED element of a plurality of connected in series or in parallel to the LED elements 251, It is connected to the positive electrode input terminal VP (+) of Acrich3, and the negative electrode terminal V _N (-) of the commercial AC power supply is connected to the negative electrode input terminal of the control chip in the driving circuit unit 252 ( Connected to VN (-)). This circuit configuration prevents electromagnetic interference. 5 illustrates a concept of an input terminal / output terminal of Acrich3, which is a control chip included in the driving circuit unit 252. FIG.

On the other hand, the TVS in the driving circuit unit 252 performs a configuration to prevent surge (Surge), as shown in FIG.

More specifically, the original AC commercial voltage is 5 to 6% higher than the normal supply voltage range, expressed as a sine wave cycle of the AC voltage, and usually lasts about 8 cycles and disappears. If the voltage rise lasts longer than 8 cycles, it is classified as an overvoltage. And voltage surges, such as impulses and spikes, that soar to thousands of volts in times of hundreds of millions of seconds, tens of millions of seconds, and millions of seconds, are called excessive surge voltages. Surge can be caused by lightning strikes or lightning strikes.Surges caused by lightning strikes around a power transmission line, creating a magnetic field around the power line or telecommunication line, generating thousands or tens of thousands of surges to reach tens of kilos. .

When lightning or lightning strikes the poles, they begin to discharge to the ground through lightning arresters installed on each pole. However, since the current discharged to the ground at such a time is so large, a potential difference of 100000 V or more is generated between the wire and the ground, and is transferred to the far direction in both directions by the wire. It is discharged by a lightning arrester installed on the telephone pole and then again by a Gap Arrester installed on the primary side of the transformer. The remaining surplus surge is sent to the secondary side of the transformer through distribution boards, distribution boxes and wiring to the office or home power outlet, and the surge is reduced to a maximum of 6000V. That is, the magnitude of 100000 V at the original source is reduced to 6000 V or less at the output.

Meanwhile, the LED device can use various LED types such as SMD, CSP, and chip on board (COB). At this time, in order to further increase the lighting efficiency, the present applicant has studied the best light efficiency using the CSP, and as a result, when the module is configured in the CSP form as shown in FIG. 7, the best light efficiency can be seen.

The controller 260 controls the camera 220, the detection sensors 231 and 232, the illumination sensor 240, and the lighting unit 250. This will be described in more detail as follows.

A signal for the sensors 231, 232, and 240 and a comment signal for dimming control of the lighting unit 250 are transmitted and received through the SPI (Serial Peripheral Interface) communication with respect to the signal that is required.
